Obesity remains a serious health problem and it is no secret that many people want to lose weight. Behavioral economists typically argue that “nudges” help individuals with various decisionmaking flaws to live longer, healthier, and better lives. In an article in the new issue of Regulation, Michael L. Marlow discusses how nudging by government differs from nudging by markets, and explains why market nudging is the more promising avenue for helping citizens to lose weight.

Armed with a computer model in 1935, one could probably have written the exact same story on California drought as appears today in the Washington Post some 80 years ago, prompted by the very similar outlier temperatures of 1934 and 2014.

Two long wars, chronic deficits, the financial crisis, the costly drug war, the growth of executive power under Presidents Bush and Obama, and the revelations about NSA abuses, have given rise to a growing libertarian movement in our country – with a greater focus on individual liberty and less government power. David Boaz’s newly released The Libertarian Mind is a comprehensive guide to the history, philosophy, and growth of the libertarian movement, with incisive analyses of today’s most pressing issues and policies.

Who’s Going to Buy All the U.S. Treasuries?

With Uncle Sam having to sell trillions of dollars worth of treasuries to finance all of the bailouts, stimuli, and normal wasteful spending, no one is sure whether foreign demand will continue. The Chinese have bluntly questioned the safety of their U.S. holdings, and foreign demand has fallen in recent months. Writes Brad Setser:

I wanted to highlight one trend that I glossed over on Monday, namely that foreign demand for long-term Treasuries has disappeared over the last few months. Consider a chart showing foreign purchases of long-term Treasuries over the past 3 months. Incidentally, the split between private and official purchases in this data should largely be ignored. The revised (i.e. post-survey) data generally have attributed nearly all the flow from 2003 to the official sector.

The rolling 3m sum bounces around a bit, but foreign demand for long-term Treasuries in November, December and January was as subdued as it has been for a long-time. Among other things, that fall in foreign demand for long-term Treasuries after October suggests — at least to me — that the big Treasury rally late last year (and subsequent sell-off this year) doesn’t seem to have been driven by external flows. Foreigners weren’t big buyers of long-term Treasuries back when ten year Treasury yields fell to around 2%.

It’s difficult to accurately predict future demand. But U.S. borrowing will be truly staggering in coming years. If international demand is down, the Treasury will have to rely on American investors. Whether the domestic market can easily absorb so much debt – and particularly, to what extent federal debt offerings will crowd out private investment during what we hope will be a recovery – are questions that our spendthrift leaders have not bothered trying to answer.
